I have a solid comp (i7, 3 GB RAM, Win XP) using PremEl 8. I am trying to make a simple 4-minute slideshow and continue getting "Error compiling movie. Unknown error." messages when trying to save as either .mpg or .avi. was unable to isolate the issue. i deleted most of the pics before i got it to work. i get low mem errors and constant program-exits. I am seriously at the point of reinstalling 7-year-old Prem El 1 as that is much more reliable. Please help.
